ABOUT ME

machine learning / deep learning enthusiast with solid computer science background and backend skills

(Currently I am very busy so I am only taking mentees seeking for long term mentorship, please DO NOT reach out to me if you are looking for only one or two session)
I can help you practice live coding interview, understanding algorothm / data structure / machine learning / deep learning in python. I am a Machine Learning Engineer in Thales with hands on machine learning experience. Currently living in SIngapore (UTC+8 timezone) Rich experience interviewing with big company and interview candidates. one of my live coding session as a interviewee is featured at interview.io as a showcase interview! https://start.interviewing.io/showcase. I was in the competitve programming team in college. I was the student with the highest grade in algorithm class. I have lots of interview experience, including Google, Roblox, Postmate, Thales and more. You can have a mock interview session with me to get a taste of a real interview and get constructive feedback. The best way to work with me is to have a long term mentorship to enhance you problem solving skills. I will cover differenct popular interview topic each week and we will work on the questions together. I will point out your blind spot, guide you to refactor your code and reach optimal solution. Working with me is more fun than working by yourself :)

Katy is amazing! She's a fabulous teacher, patient, and a great communicator. She really knows how to approach and tackle leetcode-like mental puzzle coding challenges using data structures & algorithms. You should work with her to make sure you knock out your next coding interview!

Reproduced Gatys, Leon A., Alexander S. Ecker, and Matthias Bethge. "A neural algorithm of artistic style". I redrew a photo of Wonder Woman with the style of Van Gogh. By identifying that correlations between the shallow layer feature maps is a representation of styles, I added the style loss to the objective function, fixed the weight and applied gradient descent on the initial image to minimize the objective function.
